How many cybersec professionals does it take to change a light bulb? We have dual power supplies, UPS batteries, generators and a redundant hot site in every next city. Light bulbs DO NOT go out.

S. Korea is developing a constellation of satellites that could reveal what goes on in the vicinity of supermassive black holes like never before. The #Capella satellite constellation would consist of 4 satellites orbiting at altitudes between 450 and 600 kilometers. #blackhole #LEO #satellite 📡🛰️🇰🇷

The second OCXO at 10 MHz built during the holidays. This is a different design based on an Swatch oscilloquartz 8663-XS that I found in ebay. It came back to within 0.4 ppb after starting it up again after a day. I use it for the #qo100 downconverter stabilization. #hamradio

Based on the video I've seen of the Cybertruck explosion at the Trump hotel, this looks/sounds like fireworks were ignited in the cab, not a battery fire. Most likely a darwin award candidate

Here's 24 h of FT8 monitoring, all bands 10 through 160 m, in Vancouver. MLA-30+ loop antenna. As usual, ZS2DL in South Africa, holds the distance record for a signal into my station, 16,483 km. Note PSKreporter doesn't map everything. @ai5ef.bsky.social @wa5pb.com @brian-kj7cnz.bsky.social

My wife just complimented me on my miniature wreaths, but was wondering why I was making them after Christmas. #hamradio

So, some antenna work today means I am now set up to try and receive SSTV images from the ISS. I'm up early for work, so I'm leaving #MMSSTV running overnight. There's two viable passes overnight. @kingnerd1963.bsky.social #g7kna #g4waw #STEM #ISS #SSTV #AmateurRadio #HamRadio #HamR

Mohammed Abdallah in Suez, Egypt: “Andromeda, our largest neighbor #galaxy, shot from my backyard in Bortle 8 skies. I reprocessed this shot many times but the end result is quite satisfying.” Thanks! https://ecp.earthsky.org/community-photos/entry/72472/ See more images: https://ecp.earthsky.org/

@science.org isn't just a world-class scientific journal—it's also got the best science journalists in the world writing for it (I'm only a little biased😉). They've hand-picked the most memorable stories from 2024 for this edition of #ScienceAdviser: www.science.org/content/arti...
